Phoenix (featuring R. Kelly)

While it won't be a surprise this Saturday (if he shows up at all), Kelly's presence on Weekend One was a genuinely unexpected twist for the tens of thousands of fans who just assumed that headlining act Phoenix would be joined by Daft Punk. Kelly and Phoenix went through a bumpy take on "Ignition (Remix)" that would no doubt sound smoother a second time around. As for the rest of the French band's set, they brought energy and swagger to hits old and new.
